Perfusion and oxygenation in calf muscle have been shown to be beneficial in determining severity of peripheral arterial disease and monitoring response to therapeutic interventions. However, imperfections in the saturation/inversion pulses used in ASL sequences cause significant errors in the measurement of perfusion. This works demonstrates the feasibility of modeling these imperfections in the calculation of perfusion.
